CP-properties of the Higgs-boson couplings from H + dijets through gluon fusion

الأصل · EN

At lowest order in perturbation theory, the production of a Higgs boson in association with dijets displays a strong correlation in the azimuthal angle between the dijets, induced by the CP-properties of the Higgs Boson coupling. However, the phase space cuts necessary for a clean extraction of the CP-properties in the gluon fusion channel simultaneously induce large corrections from emissions of hard radiation and thus formation of additional jets. This contribution discusses how the CP-properties of the Higgs boson coupling can be cleanly extracted from events with more than two jets, based on a technique developed from insight into the high energy limit of hard scattering matrix elements.
